About Checklists
Checklists as diagnostics and solution-finders aren't very successful, but they can be used as learning tools.
Below is one that has been successful in helping people "sharpen their eyes" in looking for risk factors. Possible solutions to each problem are also listed.
And (surprise!) there are almost always SEVERAL ways to fix a given problem. But remember our motto: "For everything you fix, you probably screw up something else."
Things to look for |
Possible solutions, (depending on further analysis) |
| Prolonged hunched or elevated shoulder while holding the phone |
Telephone headset |
Elbows splayed out (shoulder abduction) |
Lower worksurface |
| Raised or tensed shoulders | Habit or tension training Lower worksurface or keyboard Lower chair armrests Raise chair, if foot contact with the floor can be maintained |
Twisting the head to the side |
Bring viewed item closer to centerline of view |
Elbow flexed for long periods using the telephone |
Telephone headset |
Elbow or forearm resting for long periods on hard or shrp worksurface, chair armrests |
Pad or round surfaces, corners, and armrests |
Wrists bent to the sides when using side key |
Habit training |
Wrists bent back (extended) or forward (flexed) for prolonged periods |
Habit training |
Wrists or palms resting for long periods on hard or sharp keyboard or work surfaces |
Habit training |
Hands held actively over the keyboard during keying pauses |
Habit training |
Rapid, sustained, or prolonged keying |
Greater work variety |
Forceful keying, key pounding |
Habit training |
Significant amounts of hand stapling, punching, lifting, opening mail, or other forceful exertions, especially combined with awkward postures |
Mechanical aids,
such as electric stapler or punch |
Prolonged mouse use |
Greater work variety |
Prolonged sitting, especially in only one posture |
Greater work variety |
Lumbar back area not supported |
Lumbar cushion |
Feet dangling, not well supported, or a posture which seems to put pressure on the backs of the thighs |
Lower chair |
Chair backrest not used for long periods |
Check chair fit,
especially seat
pan depth and height |
Twisted torso |
Rearrange work |
Frequent or prolonged leaning or reaching |
Rearrange work |
Working with one or both arms "reaching" toward a mouse or keyboard |
Bring keyboard closer to body |
Light sources that can be seen by the worker |
Cover or shield light sources |
Reflected glare on the screen |
Shield light sources |
Too much contrast between screen and surroundings or document; worker feels relief when bright areas are shielded |
Lower ambient light levels |
Very bright ambient lighting (above 500 lux or 50 fc) or shadowed areas caused by over-illumination |
Lower ambient light levels to 200-500 lux (20-50 fc) and use task lights |
Monitor closer than approximately 65 cm (25") |
Push monitor back (enlarge
font size) |
Different viewed objects (screen, documents) at different distances from the eyes |
Use document stand or otherwise equalize distances to within about 10 cm (4") if rapid viewing changes are required |
Screen or documents not oriented perpendicular to the line of sight (tipped back slightly is even better) |
Change monitor, document stand |
Prolonged near focusing throughout the day with few far-focusing opportunities |
Move monitor back
as far as possible |
Monitor image dim, fuzzy, flickery, small, or otherwise difficult to read |
Upgrade monitor |
| Shiny, low-contrast, or small-print documents |
Improve lighting on documents if |
| Forward head posture (peering) or squinting |
Lower monitor |
Eyestrain complaints |
Check all aspects of visual |
Neck extended backwards, head tilted back, even slightly |
Remove CPU from under monitor |
Neck severely flexed (downward) |
Tilt face of monitor
back |
